It's got to be interesting, living in a virtual Faraday cage!  I'd expect one of the cell phone relay systems (like the Uniden UNI-019867) with an outdoor antenna would make your life a lot easier in bad weather..:->

SAP AND CELLPHONE RECEPTION

Very interesting post Jim.  I have another story.  Our home was built in 1953.  At that time, ceil heat was the rage and in the TVA system, electricity was about $0.03 per KW-hr.  Very inexpensive so ceil heat was definitely not that uncommon.  The owner we purchased the house from installed a central system and disconnected the previous heating system BUT did not remove the resistance wiring from the ceiling and floors. In other words, our house is one giant antenna.  I completely rewired the breaker boxes and installed a different ground system to put the system up to code.  With AT&T service for my cell, I have to go outside to get good reception or any reception.  None whatsoever inside.  Real pain when it's raining or cold.

WOW!  Do I ever!!!!  It is almost a crime how this evolution of communications equipment has been so thoroughly corrupted by impolite, rude people.  I think it is doing more to make people MORE anti-social than any other major technology phenomenon in the past century.  It is appalling to watch two younger folks having dinner together at a restaurant, and NOT speaking a word, except to the server during the entire meal visit.  They sit there w/ their eyes glued to the smartphone & their fingers being exercised to the point of carpal tunnel syndrome.  I maintain that within a few generations, according to Darwinian philosophy, people will be born WITHOUT tongues, since they're be a vestige of past eons, just like the tail & the appendix!

Good solution, but...

The pine needles resonant at 900 MHz is something I will have to remember! What I would have done differently is leave the tree where it was and relocate the antenna. I remember one time having to cut down a majestic oak tree in front of a TV station I was building because it was blocking a view of the Clarke belt from the one and only spot we could put a satellite dish. I made sure I was not around that day to see it. I always hate to cut down established trees, because they contribute positively to so many things.

A whole lot of variables affect short range radio communications, and the absorbtion of the signal by materials nearby is one of them. If you have three equations, each with the same 17 variables, it will be difficult to come up with a good solution. That is the case you have mentioned.

In the late 1950s and early 1960s, a "New" communications system came into being and Midwestern farmers were some of the first to jump on the bandwagon of Class "D" Citizens Radio Service, later called CB.

The eleven meter citizens band originally had 23 channels ranging from 26.965 MHz through 27.255 MHz giving a quarter wavelength between 9' 1 ½" and 9' 1/3" or just about the height of the typical corn stalk.  Many of the agribusinessmen noticed that they could talk further over beans or alfalfa than over green corn.

@Gorski, it would save the battery and also give you a better return on your tuition dollars to switch the phone OFF while attending classes. And the din from those people yacking away on their cell phones in the stores is a real irritation.  So just switch the phone off in poor reception areas. 

After all, who is the master and who is the servant? Think about that.

I wish someone would find a solution to improving cell eception in buildingd such as schools and supermarkets. I go to classes in a junior college that drains my cell phone battery in about an hour. Going to a supermarket or Senior Center severly limits my call phone ability to communicate. Can any of these problems be solved by using some form of your solution?
